APPARATUS FOR DISCHARGING RETORTS.

SPECIFICATION forming part of Letters Patent No. 795,202, dated July 18, 1905.

Application filed April 19, 1904. Serial No. 203,944.

To all 11.4mm, it may concern:

Beitknown that LLuoN DEGRAND, engineer, a citizen of the French Republic, residing at Paris, France, have invented certain new and useful Improvements in Apparatus for Discharging Retorts, of which the following is a specification.

This invention relates to apparatus for discharging retorts of the kind set forth in the specification of Letters Patent No. 715,004.; and it consists more particularly in improvements in mechanism for actuating and locking two consecutive racks of such apparatus.

According to this invention pins or the like and recesses or apertures are combined with or provided in the racks for the purpose of preventing or insuring, res mctively, the actuation of the racks in their proper order and at the proper times.

The improvements will now be described in connection with apparatus of the kind referred to comprising three racks hereinafter described, respectively, as the first or inn a I L ner rack, the second raek, and the third rack.

.In the accompanying drawings, Figure 1 shows diagrammatically the apparatus for discharging retorts when the three racks have all been moved home. Fig. 2 is the same view when the first rack is at the end of its stroke. Fig. 3 is the same view when the second rack is at the end of its stroke. Fig. 4 is the same view when the last rack is at the end of its stroke. Fig. 5 shows at a greater scale the device preventing or insuring at proper time the second rack to be moved along by the first one when the racks are not in gear. Fig. 6 shows the same view when the racks come into gear. Fig. 7 shows the same view when the racks are in gear. Fig. 8 is a side elevation of one of the racks and the parts cooperating therewith, the rack being in this instance at the end of its stroke. Fig. 9 is a transverse section of the apparatus through the line D D, Fig. 8. Fig. 10 is a transverse section through the line A A, Fig. 8. Fig. 11

is a transverse section through the line B B,

Fig. 8, showing the parts in the position assumed thereby during the forward motion of the first rack. Fig. 12 is a transverse section 5 through the line C C, Fig. 8.

Assuming that the three racks a Z) 0 have all been moved completely home, then when the apparatus is set in motion for the purpose of commencing the discharging operation the first or inner rack a, which is alone in engagement with its toothed driving-wheel a, is set in motion. The second rack 7) is not driven by friction. It is, in fact, kept back by a first pin (Z, which is held at each end in a bearing a, formed in the third rack 0 and resting on the first rack a. This pin extends through an aperture f, formed in the second rack 7). The third rack is itself kept back in the same manner by a second pin (1, which is 5 held at each end in a bearing formed in a guard-plate g, that is fixed to the framing.

Then the first rack a is nearing the end of its stroke, a recess it, formed in the upper part of this rack a, arrives underneath the lirst 7 pin. The latter moves down into this recess and can then be moved along by and with the first rack a by reason of the shape of the hearing a, which comprises a vertical portion and a horizontal portion connected together by a curved portion. A shoulder a? at the rear of the first rack a bears at this moment against a shoulder 7', formed on the forward portion of the second rack Z), and allows this second rack b to be moved along by the first rack a until the second rack 7) engages its pinion 7/. Almost at the same moment the driving-pinion a of the first rack a ceases to engage that rack a. The second rack 7) moves forward and pushes the first rack c, the connection be- 5 tween these tWo racks being insured by means of the first pin, which is engaged on one side in the aforesaid aperture f of the second rack b and on the other side in the aforesaid recess 7b of the first rack (4. During the forward 9 movement of the second rack b the third rack c is kept in its place. When the second rack b is about to arrive at the end of its stroke, the actuation of the third rack c and its engagernent with its driving-pinion c are effected in the same manner as in the case of the second rack 71. At the end of its stroke the third rack is kept in place by abutmentagainst a fixed stop h. For the return stroke the same movements take place in the reverse directions. The pins return readily of themselves into their first positions by reason of the curve that connects the horizontal portion and the vertical portion of their bearings. The pins may be easily inserted and removed from their bearings by means of lateral apertures provided for this purpose in the machine.

By reference to Figs. 9, 1O, 11, and 12, and particularly to Fig. 9, the arrangement of the pinions and their operative position with re spect to the different extensible parts is clearly shown, and the avoidance of interference of the pinion a/ With the second and third sections and also of the pinion 7/ with the third section is illustrated.

Having thus described and ascertained the nature of my invention and in What manner the same may be performed, I declare that What I claim is In an apparatus for discharging retorts, mechanism for providing a properly-timed operation of the apparatus, the said mechan ism consisting of a series of racks all of Which are movable and provided with locking means to couple the same for unitary sliding movement at intervals, said locking means consisting of pins projecting from and openings formed in the several racks, the pins consecutively and loosely engaging the openings of the racks and also operative in part to prevent one rack from being driven by the friction of an adjacent rack before the latter rack is at the end of its stroke.

In testimony whereof I have hereunto set my hand in presence of tWo subscribing wit- DOSSQS.
